  But  this will not be easy I fear !
   print_symbol_info calls
    type_print
  which in turn just uses
     LA_PRINT_TYPE()

   but the problem is that I am not sure that using source language would
be a good thing for
  all calls to type_print !
   I only thought this would be helpful for print_symbol_info
because there you can get several different sources.
  But I would not like to have a 
 "p PASCAL_RECORD"
  giving a pascal format if I am currently inside some C code
that uses a global pascal variable !

   The problem is that even if the case of args of a function is quite clear 
I suspect that in other cases it will no be so easy to decide 
when we should use current_language and when 
we should use the source file langage !
